Description
본 발명은 폴리카보네이트 광확산 수지 조성물 및 이를 포함하는 폴리카보네이트 수지 성형품에 관한 것이다.The present invention relates to a polycarbonate light diffusion resin composition and a polycarbonate resin molded article including the same.
폴리카보네이트 수지는 상업적으로 널리 사용되는 투명 플라스틱 중의 하나로, 사출성형이나 압출성형에 의해 유리 대체 플라스틱, 용기, 자동차 램프 커버 등의 용도로 많이 사용되고 있다. 이러한 광학적 용도 중, 실내외 조명등, 자동차 내외장등, 건축실내등의 기본재료로 적용시 요구되는 물성은 높은 헤이즈와 전광선 투과율이다.Polycarbonate resin is one of the commercially widely used transparent plastics, and is widely used for glass replacement plastics, containers, automobile lamp covers, etc. by injection molding or extrusion molding. Among these optical uses, physical properties required for application as basic materials such as indoor and outdoor lighting, automobile interior and exterior lighting, and building interior are high haze and total light transmittance.
헤이즈가 낮을 경우 제품 내부의 구조물이 보이게 되며, 사용자로 하여금 눈부심을 유발 할 수 있기에 조명용 커버로 사용시에 중요한 물성이라 할 수 있겠다.When the haze is low, the internal structure of the product is visible, and it can be called an important property when used as a lighting cover because it can cause glare to the user.
또한 전광선 투과율이 낮은 광확산 수지 커버를 적용할 경우 조명의 효율이 낮아져 어두워지고 이를 해결하기 위하여 광원의 수를 늘리거나 고휘도의 광을 사용해야 하는 제한이 있기에 전광선 투과율은 중요한 물성이라 하겠다.In addition, when the light diffusion resin cover with low total light transmittance is applied, the lighting efficiency becomes dark, and the total light transmittance is an important property because there is a limit to increase the number of light sources or to use high luminance light to solve this problem.
또한, 조명의 사용특성상 사용상의 결함으로 인한 발화 또는 인화에 대한 안정성을 확보하기 위하여 종래의 기술은 할로겐성(브롬화, 염소화) 난연제를 사용하여 난연성을 확보하였지만, 발화시 할로겐성 배출가스로 인하여 인체에 치명적인 유해성을 나타내는 문제점이 있다.Further, in order to ensure stability against ignition or flame due to defects in use due to the nature of the use of the illumination, the flame retardancy is secured by using a halogen-based (brominated or chlorinated) flame retardant in the prior art. However, There is a problem indicating a lethal hazard.
따라서, 폴리카보네이트 수지가 가지고 있는 본연의 높은 충격강도를 저하시키지 않으면서 높은 전광선 투과율과 높은 헤이즈 뿐만 아니라, 우수한 난연성 및 친환경적인 특성을 나타낼 수 있는 기술개발이 요구되고 있다.Therefore, there is a demand for development of a technique capable of exhibiting not only a high total light transmittance and a high haze but also excellent flame retardancy and environment-friendly characteristics without deteriorating the inherent high impact strength of the polycarbonate resin.
본 발명은 높은 전광선 투과율과 헤이즈 및 우수한 충격강도를 나타내면서도 우수한 난연성과 친환경적인 특성을 나타내는 폴리카보네이트 수지 조성물을 제공하고자 한다.The present invention is to provide a polycarbonate resin composition showing a high total light transmittance and haze and excellent impact strength while showing excellent flame retardancy and environmentally friendly properties.

As a result of measuring physical properties, as shown in Table 2, the flame-retardant polycarbonate light-diffusion resin compositions of Examples 1 to 3 according to the present invention are polymethylsilsesquioxane bead light diffusing agent and poly The methylmethacrylate bead phase light diffusing agent, the potassium perfluorobutane sulfonate compound, the potassium diphenyl sulfone sulfonate compound and the optical brightener are included in the optimum ranges, respectively, to express excellent haze, total light transmittance and impact strength. At the same time, it was confirmed that excellent flame retardancy was achieved.
특히 실시예 1~3의 경우 우수한 전광선 투과율과 99% 이상의 우수한 헤이즈를 가지며 동시에 우수한 충격강도를 나타냄을 확인 할 수 있었고, 초기 착색이 적으며 2.0mm에서 V0 난연성을 확보하였음을 확인할 수 있었다.
